Missing window.PromiseRejectionEvent API

[chenxinyanc]

Describe the bug While there is ErrorEvent provided by happy-dom, there seems to be a lack of PromiseRejectionEvent from window.

To Reproduce Use the following code in vitest with environment: "happy-dom" as vitest config.

console.log(window.ErrorEvent);
console.log(window.PromiseRejectionEvent);

Expected behavior I should see both logs to be non-undefined.
